Hi,

We ar= e doing POC on Cassandra for our business needs. We also need some kind of = notification when a column/attribute is modified (insert/update/delete) of = a table.

Thanks for sharing information about CDC.= Could you please point us to some example of how to implement this in Cass= andra 3.9.


Thanks and Regards

Alternatively if you need a notification system of = new mutation, there is a CDC feature, available since 3.9 only (maybe not p= roduction ready yet)
